H5P embedded directly (using embed code) have height=0 in the app

You will need to test this issue in 2 devices at the same time. It doesn't matter if they're Android or iOS. For iOS, please remember to go to the iOS Settings > Moodle and enable "Allow Cross-Website Tracking". Setup In web as admin, create a new course. This bug doesn't happen in certain conditions so it's better to create a new course. Enrol a student in the course. In this course, create an H5P activity. Make sure to enable "Embed button" in "H5P options". Open this H5P and wait for it to load. Click the "Embed" button at the bottom and copy the HTML code. Create a label in the same course. In the label text, click the button to display the HTML code and copy the code you copied in the previous step. Before saving, check if the HTML iframe has something like "height="388"". If it does, remove it (you can leave style="height: 0px"). This is to ensure that the bug described in this issue happens. Save the label. Check that the H5P package is displayed correctly. Test In the app, login as the same student in both devices. In device 1, open the course and go to the label. Check that the H5P package is displayed correctly. In device 2, and before 6 minutes pass since the last step, open the course and go to the label. Check that it displays the login form because the auto-login failed (you already used auto-login in device 1). Enter the username and password in the iframe and send them. Check that now the H5P package is displayed correctly.
